In this tree, the root is the base cuboid. For a cuboid, it may have many legal parent cuboids. We should choose the {color:#f79232}best parent {color}cuboid as its parent in this tree. Then how to define the best? It's related two rules as follows: > * If we know the row count, choose the one with the least row count > * Otherwise, choose the smallest cuboid > Based on the cuboid tree, we introduced a new cuboid scheduler called {{TreeCuboidScheduler}}. And both cube building & query can be based on {{TreeCuboidScheduler}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
